The aim of this study was to report the role of a new ultrasound sign, the distance between the choroid plexus (CP) of the third ventricle and the distal part of the CC, in identifying fetuses with partial agenesis (pACC) or hypoplasia of CC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective multicenter case\u2013control study including fetuses with pACC or hypoplasia of the CC confirmed at post\u2010natal imaging or autopsy. The distance between the CP of the third ventricle and its ratio with the length of the CC were compared with unaffected cases on stored images assessed by 2 different examiners. Intraclass correlation, Bland\u2013Altman, univariate, and multivariate logistic regression analyses were used to analyze the data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      One hundred and four (29 with pACC or hypoplasia of the CC and 75 controls) were included in the analysis.
